BUFFER FOR THE BOTTOM 2.' ,e s f s or sssnns This invention relates towindow sashes and'guides therefor and has for its object a particularlysimple, economical and elicient buifer for the lower edges of the bottomrails or sashes, which builer readily conforms to e of a window sash andframe sills of different inclines and also to unevennesses of variationsin the surface of the sill whether inherent in the sill or produced bydust, cinders etc. accumulating on the sill.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed. 'l

In describing this'invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in alltheviews.,

Figure 1 is a fragmentary perspective View embodying this invention.

Figure 2 is a fragmentary sectional View through the bottom rail.

Figure 3 is a fragmentary elevation of one of the corners of the sash.

This invention comprises generally a buffer comprising a tubular bodysecured to the lower edge of the bottom rail of the sash,

the body being` collapsible and having,

resilient walls particularly having a resilient bottom wall for engagingthe sill, the side walls being also exible and resilient and a lip orflange extending lengthwise of the body at the rear edge of the bottomwall or at the rear lower corner of the body for engaging the sill, theconstruction being such that the body andthe liange conform to sills ofvarious inclines and also readily conform tounevennesses of the surfaceof the sill, thus making the edge along the bottom rail thereofsubstantially air tight and Weather tight when the sash is closed.

1 designates the sash, and 2, the frame, the frame including the usualsill 3 and sash guides 4 in the form of channels at the opposite sidesof the sash, one of such guides being shown in the drawings. The sashmay be of any suitable construction and includes the usual top andbottom rails and stiles.

5 designates the bottom rail and 6 one of the Stiles.

bulging bottom wall 15 7 designates the' glazing.

up of sheet metal open at its lower edge and having inturned flanges 8at its lower edge. It is also shown as provided with an internal brace9. The sash is formed up of light sheet metal as brass and the bracesare utilized to stiften the bottom rail particularly as it is open atits lower edge. The construction of the sash forms no part of thisinvention.

10 designates the buffer including a tubular body which is resilient andcollapsible and a iiexible resilient lip 11 extending lengthwise of thebody and offset from the central vertical plane thereof so that the bodyand the lip are in general form Q-shped in cross section. The body andlip are usually formed of rubber and normally forms an extension of theouter rear wall of the body. rlhe body is rigidly secured to the loweredge of the bottom s. HENDERSON, or smcusn,

rail by suitable means here shown as a base 12 formed integral with thebody and extending into the lower o en edge of the bottom rail andinterlocked wit the bottom rail by means of the inturned flanges 8 whichextend into grooves in the base 12.

Although the tubular body may be circular in general form, it is here"shown as provided with normally flat outer and inner sides 13 and 14flush with the outer and inner faces of the bottom rail and with adownwardly which turns upwardly and then downwardly at 16 where it joinsthe flange 11 and the upright wall'13. This bottom wallv15 is resilientand flexible and also the outer, and inner walls/13, 14 are flexible.The passage 17 of the tubular body, it maybe circular, is, in order tobring out to the highest degree the conformity of the buier to thedifferent inclines of the sills and the variations or unevennesses ofthe surface thereof formed irregular with tion at 18 where the lip 11joins the body of the buiier strip, the passage being so formed as topermit the bottom wall 15 to lie iatwise on the sill snugly and conformto the sill and to cause the lip l1 to also lie flatwisev onthe sillregardless of its incline and variation or unevenness thereof and forman extension of although a corner porible and collapsible member havinga iiexible` the bottom wall when compressed against the sill.

The lip 11 terminates at 19 short of the ends of the buffer strip sothat the end portions 20 of the body extend into the channels of thewindow guides 4 behind the outer walls 21 thereof while the lipterminates at the edges 22 of the walls 21. Ilhus, the tubular body canconform to the walls of the channels ot the guides and coact with thelip 11 or the terminal 19 thereof to render the sash weather tight atthe corners thereof adjacent the guide.

lt is to be understood that it has been particularly difficult to rendera sash entirely weather tight at the corners thereof.

ln operation, the buier is normally in the form shown in Figure 2, whenthe sash is raised with the lip 11 in line with the outer wall 10 of thebody of the bader. vWhen the sash is closed against the sill, the bottomwall 15 collapses or assumes the position shown in Figure 2 snuglyfitting against the sill regardless of whether the sill is level orinclined various degrees. Also, the lip snugly engages and pressesagainst the sill. rlhe rear wall of the tubular body also bulgesoutwardly against thesurface 23 of the sill. The

vend portions of the strip during the collapsing action also conform 'tothe walls of the window guides while the terminal 19 of the lip coactswith the ed es 22`0 the guide to further render the sas weather tightwhen closed.

What we claim is:

1. The combination with a sash and window frame having a sill, of-abuffer strip extending along the lower edge of the bottom rail of thesash, said strip comprising a tubular iiexresilient lip extending fromthe outer lower corner thereof.

2. Thecombination with a sash and window frame having a sill, of abui'er strip extending along the lower edge of the bottom rail of thesash, said strip comprising a tubular flexible and collapsible bodyhaving a flexible resilient lip extending from the outer lower cornerthereof normally forming an extension of the outer upright-wall of thebody and movable as the body and the .lip compress against the sill in aposition where it forms an extension of the bottom wall of the body.

3. The combination with a sash and window frame having a sill, of abuffer strip extending along the llower edge of the bottom rail of thesash comprising a collapsible resilient tubular body having a base Jforrigid attachment tothe bottom rail of the sash, Vand a lengthwise lipextending along the lower outerzcollllr of the body and normally formingan extension of an uprightl side of the body. 4. The combination with asash and win- 'the bottom rail of the sash,the body having a resilientlip extending lengthwise thereof for engaging the sill, the body withthe lip being @-shape in general form in crosssection.

5. The combination with a sash and window frame having a sill, of abuiifer strip extending along the lower edge of the bottom rail of thesash comprising a tubular collapsible body having a yielding bottom wallfor engaging the sill and a flexible resilient lip extendin lengthwiseof the body at the rear edge of t e bottom wall and normally forming anextension of the rear upright wail of the tubular body and movable intoposition to form an extension of the bottom wall as the bu'er and lipcompress against the sill.

6. The combination with a sash and window frame having a sill and sashguides in the form of channels, of a buier strip extending along thelower edge of the bottom rail of the sash, said strip comprising atubular dexible and collapsible member havin a flexible resilient lipextending from t e outer lower corner thereof, said lip terminatingshort of the ends of the body whereby the ends thereof are adjacent the"inner edges of the "and cllapsible member having a iiexible andresilient lip extending from the outer lower corner thereof normallyforming an extension of the outer upright wall of the body, said lipterminating short of the ends of the body whereby the ends thereof areadjacent the inner edges of the outer walls of the window guides andtheend portions of the body without the li extend into the channels.

8. The com ination with a sash and window frame having a sill and sashguides in the form of channels, of a buffer strip extending along thelower edge of the bottom rail of the sash comprising a resilient tubularbody having a base for rigid attachment to the bottom rail of the sash,the body having a. resilient lip extending lengthwise thereof forengaging the sill, the body with the lip being Q- shape in general formin cross section, said lip terminating short ofthe ends of the bodywhereby the ends thereof are adjacent 'the inner edges of the outerwalls of the window guides, and the end portions of the body without thelip extend into the channels.
